In this study, the size effects of the Graphene
nanoparticles (GNP) doped into a paraffin type organic phase change material
(PCM) on thermal properties were examined. The thermal conductivities,
melting/solidification temperatures and melting/solidification latent heats of
the GNP/PCM composites, which were obtained by incorporating GNP nanoparticles
with three different sizes into an organic PCM in mass fractions of 1%, 3% and
5%, were measured. The changes obtained in thermal properties were determined by
referring to the non-doped PCM data. The results obtained showed that in low
PCM mass fractions, thermal conductivity enhancement was a function of both
surface area and thickness of the GNP nanoparticles. In addition, it was
determined that thicker nanoparticles formed a more efficient conduction
network at high PCM fractions. The reflections of the enhancements obtained in
thermal conductivity on thermal performance were also determined in the study.
 
Enhancements in thermal
conductivity depending on the increase in thickness of GNP were obtained as 6.3%,
107.5% and 113.7% for 5% GNP(1-5nm)/ PCM, 5% GNP(6-8nm)/PCM and 5% GNP(11-15nm)/PCM
composites, respectively. These thermal conductivity enhancements resulted
performance increase in the energy storage unit around 5.5%, 18.3% and 20%
respectively.

Bu çalışmada, parafin
tipi bir organik Faz Değişken Malzeme (FDM) içerisine katkılanan Grafen
nanoparçacık boyutunun termal özellikler üzerindeki etkileri incelenmiştir. Üç
farklı boyuta sahip GNP nanoparçacıkların organik bir FDM içerisine %1, %3 ve
%5 kütle bölüntülerinde katkılanması suretiyle elde edilen GNP/FDM
kompozitlerinin ısıl iletkenlik, erime/katılaşma sıcaklıkları ve
erime/katılaşma gizli ısıları ölçülmüştür. Termal özelliklerde elde edilen
değişimler katkılanmamış FDM verileri referans alınarak belirlenmiştir. Elde
edilen sonuçlar, düşük GNP kütle bölüntülerinde ısıl iletkenlik
iyileştirmesinin hem GNP nanoparçacık yüzey alanının hem de kalınlığının bir
fonksiyonu olduğunu göstermiştir. Buna ilave olarak, daha kalın
nanoparçacıkların yüksek FDM kütle bölüntülerinde daha etkin bir iletim ağı oluşturdukları
belirlenmiştir. Çalışmada ayrıca ısıl iletkenlikte elde edilen iyileştirmelerin
termal performansa yansımaları da belirlenmiştir. GNP nanoparçacık
kalınlığındaki artışa bağlı olarak ısıl iletkenlikteki iyileşmeler; 5%
GNP(1-5nm)/ FDM, 5% GNP(6-8nm)/FDM ve 5% GNP(11-15nm)/FDM kompozitleri için
sırasıyla %6.3, %107.5 ve
  %113.7 olarak
elde edilmiştir. Bu ısıl iletkenlik iyileştirmeleri, bir enerji depolama
biriminde sırasıyla %5.5,% 18.3 ve % 20 civarında performans artışı
sağlamıştır.
